Abstract

Problem solving skills are one of the essential competencies possessed by a student. This study aims to develop learning materials that can improve students problem solving skills. The learning materials were developed by following the problem posing type post solution posing principle. The development research method used is 4D (define, design, development, and disseminate). The subject of the research were 43 senior high school students. The research instrument used was a questionnaire validity sheet, a practicality sheet, and a problem solving test. The evaluation results of the learning materials feasibility were considered very feasible based on the assessment of 12 experts, who were divided into three learning design experts, three linguists, three media experts, and three material experts. The tested learning materials were effective in improving students problem solving skills, with an N-gain of 0.43 in the (medium) category. The results of the practicality of the learning materials on student responses obtained a score of 84.72% in the very good category and, based on the three responses from the physics teacher, obtained a score of 91.67% in the very good category. The results in this study can be used as a reference in developing learning materials on other physics topics.
